Specification of Letters Patent. I Patented DIay 16, 1911,

Application filed December 10, 1909.

Serial No. 532,360.

To all whom it may concern: 7

Be it known that I, lVILLIAM S. GRAHAM, a citizen of the United States,residing at Canton, in the county of Fulton, State of Illinois,haveinvented certain new and useful Improvements in Gang-Flows, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

My invention relates to gang plows of engine. It is sometimes desirableto have the engine farther to one side or the other relative to the plowthan at other times,

' of the work, and provision must be made for.

depending upon the width of the engine used, for example, or upon otherconditions this adjustment in the connections between the engine and theplow. This has been accomplished heretofore by connecting the plow tothe engine by means of a pair of chains which converged toward their forlvard ends and'werethere connected to the engine, the chains being longenough sothat when one chain was shortened more or less so as to shiftthe engine farther to that side of the plow the chains would still worksatisfactorily. The result has been to place the platform of the plow atsome little distance from the platform of the engine, so that .the

operator has not been able to step from one to the other without greatinconvenience and danger to himself. On the other hand,

in cases where both chains have been shortene'd; up so, as to bring thetwo platforms into convenient relation closer to each other, thenecessary adjustability in the connect-ion has been lacking. 1

Itis the object of my'invention' to provide 'a new "and improvedconstruction of plow frame by reason of which, when such plowv isconnected up with an ordinary traction engine such asare now in commonuse, the platform of the plow may extend to within a very short distanceof the platform of thecngine so as to enable the operator to step easilyand without danger from one to. the other, at the same time maintainingthe desired adjustability in such connection. I have accomplished. thisobject by the means shown in the drawing and hereinafter specificallydescribed. I

That which I believe to be new will be set forth in the claims.

iron as shown.

that class adapted to be drawn by-a traction cured to said oblique bar10 near one end The drawing is a top or plan View of the frame of agang-plow embodying my improvements with "one plow-beam and itsaccompanying parts connected'to the frame.

Referring to the drawing,10 indicates the. obliquebar of the plow towhich the plow-beams are adapted to be connected, being preferably intheform of an angle- -11 indicates a bracket sethereof. I

12'13 indicate two bars comprising the plow-beam pivotally connected attheir front ends to the bracket 11, and connected at their rear ends toa plow 14 in any approved manner.

15 indicates a caster-wheel connected to the bar 12 and provided with alever 16 by which it may be shifted up or down relative to said bar asdesired.

The parts so far described are preferably vofthe form described andclaimed in my applicat-ion for Letters Patent on gang-plows,

filed Nov. 1, 1909, Serial No. 525,720, and

form no part of my present invention, and it is not believed to benecessary to describe them further in detail herein. It, will, ofcourse, be understood that any other desired form of plow and plow-beammay be employed if desired. I

Coming now to the framework of the plow, l718 indicate two heavy barsconnected at their rear ends by bolts, or in any other suitable manner,to the oblique bar 10 near the opposite ends thereof, said barsextending from the oblique bar 10 for-\ ward parallel with the line ofthe draft and being turns or bent so as tolconverge at their forwardends, which are suitably connected to abracket 19.

20 indicates a heavy brace-bar extending obliquely from about thecentral portion of the bar 17 to about the center of the oblique barl0,'being' suitably connected at "its ends to said parts.

2l22 indicate axles suitably secured to the oblique bar 10 and to thebars 17*18, respectively. j

232t indicate carrying-wheels journaled upon the axles2l22,respectively.

2526 indicate two bars connected at their forward ends in any suitablemanner to a pin 27, which is journaled in the bracket manner.

29 indicates a brace-rod connecting the.

rear ends of the bars 25 26, and holding them firmly in positionrelative to each other. Y

30-31 indicate rollers journaled in the rear ends of the bars 25-26.

indicates a bar connected at its ends to the bars Il -l8, with. itscentral portion formed in the ,arc of a circle about the pin 27 so thatthe'reliers 30--31' bear upon the lower edgeof the arc'shaped portion ofthe bar 32.

33 indicates a brace-bar connected at one end to the end-of the obliquebar 10, and connected to the bar 18.

34.-.35 indicate hitch-irons connected to the bars 17.-18 respectively,at the points where saidsbars 17'18 begin to converge, the hitch-iron 35in the construction shown being integral with the brace-bar 33.

36-37 indicate flexible connections, shown in the form of chains,connected at their rear ends to the hitch-irons 34--35, respectively;They converge toward their forward ends, and are there connected to ahitch-ring 38.

It will be understood that in use .a platform will be provided coveringthe framework of the plow, which may be secured thereto in any suitablemanner, and it is not believed to be necessary to illustrate or describethis feature of the plow since it forms no 'part of the invention. Suchplatform, extending as it may to the forward end of the framework of'theplow, would extend to within a short distance of the hitch-ring 88,which would ordinarily be attached to the engine-a very little distancein the rear of the engine platform. In this way the plat form of theplow is brought quite close to the engine platform, at the samemaintaining the chains 3637 of sufliclent length to insure the desireddegree of adj ustabllity in the connection between the engine and the vplow.

What I claim as my invention and desire to secure by Letters Patent is,-I

1. In a gang plow, the comblnatlon w th a frame comprising an obliquebar towhich the plow-beams are adapted to be attached, a pair of barsone attached to sa d oblique bar near each end thereof, said last-namedbars extendin bar parallel with the line of draft and belng turned neartheir forward ends into convergence with one another, and a bracket comnected to said bars at their forward ends, of

forward from said oblique scenes a pair of flexible connectionsconnectedto and frame. at about the point wherezsaid i bars begin. toconverge;

2. In a gang-plow, the combination with a frame comprising an obliquebar to'which the plow beams are'adaptedto be attached,

turned near their forward ends into cor V'ergence with one another, abracket connected to said bars at their: forward ends, and acaster-wheel ournaled in said bracket,

of a pair of flexible connections attached to Sald frame at about thepoint where-saidbarsbegin to converge.

3. In a gang plow, the combination wit-h .a frame whose sldes convergetoward the forward end,- carrying wheels mounted thereon, a caster-wheelmounted in the for ward end of said frame, and a plurality of plowsmounted on said frame, of a pair of flexible connections attached tosaid frame in rear of the point of said frame and extending forwardtherefrom.

4:. In a gang plow, the combination with a frame whose sides convergetoward the forward end, a caster-wheel mounted in the forward end ofsaid frame, an arc-shaped bar extending transversely of said frame,

and anti-friction devices carried by said caster-wheel and adapted to.engagesaidtransverse-bar, of a pair. of flexible connections attached tosaid' frame in rear of the point of said frame and extending forwardtherefrom.

5. In a gang-plow, the combination with a frame comprising an obliquebar to which the plow beams are adapted to be attached, a pair of barsone attached tosaid oblique bar near each end thereof, said last-namedbars extending forward from said oblique bar parallel with the line ofdraft and being I turned near their forward ends into convergence withone another, a bracket con-- the point of said frame and extending forward therefrom.
